`v2.17.0`

Compare Source

2.17 is a small release that is the first to support python 3.11 officially with the addition of TryStar nodes.

There's still two new default checks: bad-chained-comparison and implicit-flag-alias, one of them already fixed a previously undetected bug in sentry.

Thanks to the community effort our documentation is almost complete, and almost all messages should have a proper documentation now. A big thank you to everyone who participated !

The next release is going to be 3.0.0, bring breaking changes and enact long announced deprecations. There's going to be frequent beta releases, before the official releases, everyone is welcome to try the betas so we find problems before the actual release.

Summary -- Release highlights

In 2.16.0 we added aggregation and composition understanding in pyreverse, and a way to clear the cache in between run in server mode (originally for the VS Code integration). Apart from the bug fixes there's also a lot of new checks, and new extensions that have been asked for for a long time that were implemented.

If you want to benefit from all the new checks load the following plugins::

pylint.extensions.dict_init_mutate,
pylint.extensions.dunder,
pylint.extensions.typing,
pylint.extensions.magic_value,

We still welcome any community effort to help review, integrate, and add good/bad examples to the doc for #5953. This should be doable without any pylint or astroid knowledge, so this is the perfect entrypoint if you want to contribute to pylint or open source without any experience with our code!

Last but not least @clavedeluna and @nickdrozd became triagers, welcome to the team !

What's new in Pylint 2.16.0?

Changes requiring user actions

The accept-no-raise-doc option related to missing-raises-doc will now be correctly taken into account all the time.

Pylint will no longer raise missing-raises-doc (W9006) when no exceptions are documented and accept-no-raise-doc is true (issue #7208). If you were expecting missing-raises-doc errors to be raised in that case, you will now have to add accept-no-raise-doc=no in your configuration to keep the same behavior. Closes #7208

New Features

Added the no-header output format. If enabled with --output-format=no-header, it will not include the module name in the output. Closes #5362
Added configuration option clear-cache-post-run to support server-like usage. Use this flag if you expect the linted files to be altered between runs. Refs #5401
Add --allow-reexport-from-package option to configure the useless-import-alias check not to emit a warning if a name is reexported from a package. Closes #6006
Update pyreverse to differentiate between aggregations and compositions. pyreverse checks if it's an Instance or a Call of an object via method parameters (via type hints) to decide if it's a composition or an aggregation. Refs #6543

New Checks

Adds a pointless-exception-statement check that emits a warning when an Exception is created and not assigned, raised or returned. Refs #3110
Add a shadowed-import message for aliased imports. Closes #4836
Add new check called unbalanced-dict-unpacking to check for unbalanced dict unpacking in assignment and for loops. Closes #5797
Add new checker positional-only-arguments-expected to check for cases when positional-only arguments have been passed as keyword arguments. Closes #6489
Added singledispatch-method which informs that @singledispatch should decorate functions and not class/instance methods. Added singledispatchmethod-function which informs that @singledispatchmethod should decorate class/instance methods and not functions. Closes #6917
Rename broad-except to broad-exception-caught and add new checker broad-exception-raised which will warn if general exceptions BaseException or Exception are raised. Closes #7494
Added nested-min-max which flags min(1, min(2, 3)) to simplify to min(1, 2, 3). Closes #7546
Extended use-dict-literal to also warn about call to dict() when passing keyword arguments. Closes #7690
Add named-expr-without-context check to emit a warning if a named expression is used outside a context like if, for, while, or a comprehension. Refs #7760
Add invalid-slice-step check to warn about a slice step value of 0 for common builtin sequences. Refs #7762
Add consider-refactoring-into-while-condition check to recommend refactoring when a while loop is defined with a constant condition with an immediate if statement to check for break condition as a first statement. Closes #8015

Extensions

Add new extension checker dict-init-mutate that flags mutating a dictionary immediately after the dictionary was created. Closes #2876
Added bad-dunder-name extension check, which flags bad or misspelled dunder methods. You can use the good-dunder-names option to allow specific dunder names. Closes #3038
Added consider-using-augmented-assign check for CodeStyle extension which flags x = x + 1 to simplify to x += 1. This check is disabled by default. To use it, load the code style extension with load-plugins=pylint.extensions.code_style and add consider-using-augmented-assign in the enable option. Closes #3391
Add magic-number plugin checker for comparison with constants instead of named constants or enums. You can use it with --load-plugins=pylint.extensions.magic_value. Closes #7281
Add redundant-typehint-argument message for typing plugin for duplicate assign typehints. Enable the plugin to enable the message with: --load-plugins=pylint.extensions.typing. Closes #7636

Messages sent to reporter are now copied so a reporter cannot modify the message sent to other reporters. Closes #7214
Fixed a case where custom plugins specified by command line could silently fail. Specifically, if a plugin relies on the init-hook option changing sys.path before it can be imported, this will now emit a bad-plugin-value message.

Fix false positive for redefined-outer-name when aliasing typing e.g. as t and guarding imports under t.TYPE_CHECKING. Closes #7524
Fixed a crash of the modified_iterating checker when iterating on a set defined as a class attribute. Closes #7528
Use py-version to determine if a message should be emitted for messages defined with max-version or min-version. Closes #7569

Fixes edge case of custom method named next raised an astroid error. Closes #7610

Fix a crash when a child class with an __init__ method inherits from a parent class with an __init__ class attribute. Closes #7742

Internal Changes

Add and fix regression tests for plugin loading. This shores up the tests that cover the loading of custom plugins as affected by any changes made to the sys.path during execution of an init-hook. Given the existing contract of allowing plugins to be loaded by fiddling with the path in this way, this is now the last bit of work needed to close Github issue #7264. Closes #7264

`v2.15.5`

What's new in Pylint 2.15.5?

Release date: 2022-10-21

False Positives Fixed

Fix a false positive for simplify-boolean-expression when multiple values are inferred for a constant.

Closes #7626

Other Bug Fixes

Remove __index__ dunder method call from unnecessary-dunder-call check.

Closes #6795
Fixed a multi-processing crash that prevents using any more than 1 thread on MacOS.

The returned module objects and errors that were cached by the linter plugin loader cannot be reliably pickled. This means that dill would throw an error when attempting to serialise the linter object for multi-processing use.

Closes #7635.

Other Changes

Add a keyword-only compare_constants argument to safe_infer.

Refs #7626
Sort --generated-rcfile output.

Refs #7655

`v2.15.4`

Closes #7529

Other Bug Fixes

Fix bug in detecting unused-variable when iterating on variable.

Closes #3044
Fixed handling of -- as separator between positional arguments and flags. This was not actually fixed in 2.14.5.

Closes #7003, Refs #7096
Report no-self-argument rather than no-method-argument for methods with variadic arguments.

Closes #7507

Closes #7311
--help-msg now accepts a comma-separated list of message IDs again.

Closes #7471

`v2.15.2`

Compare Source

Fixed a case where custom plugins specified by command line could silently fail.

Specifically, if a plugin relies on the init-hook option changing sys.path before it can be imported, this will now emit a bad-plugin-value message. Before this change, it would silently fail to register the plugin for use, but would load any configuration, which could have unintended effects.

Fixes part of #7264.
Fix used-before-assignment for functions/classes defined in type checking guard.

Closes #7368
Update modified_iterating checker to fix a crash with for loops on empty list.

Closes #7380

Closes #3299
Fix false positive for too-many-function-args when a function call is assigned to a class attribute inside the class where the function is defined.

Closes #6592
Fix used-before-assignment for functions/classes defined in type checking guard.
